Pustular Psoriasis

Pustular Psoriasis

Pustular psoriasis, as the name suggests, is characterized by clearly defined, raised bumps on the skin that are filled with pus, and the skin around these bumps is red in appearance.  It is important to note that the pus is not the result of an infection, nor is it contagious.  The pus consists of white blood cells.  This form of psoriasis is not common, and it affects people of all races but is usually limited to adults.  Pustular psoriasis can be generalized or localized (appearing in limited areas such as the hands and feet).  Pustular psoriasis tends to go in cycles, where the skin reddens and become irritated, and the pustules follow.  The triggers for this form of psoriasis can include, but are not limited to systemic steroids and the sudden withdrawal of steroids, infections, topical skin irritants, pregnancy, emotional stress, and overexposure to ultraviolet light.  This type of psoriasis can be broken down further into three different types:  Generalized, Von Zumbusch, Palmoplantar Pustulosis (PPP), and Acropustulosis.  All types of psoriasis can be emotionally upsetting to the patient, but especially pustular psoriasis due to the puss filled blisters and how they appear to others who are ignorant about this skin disease.  It is important to seek treatment from a dermatologist who not only has lots of experience with psoriasis patients, but also one who keeps abreast research and treatment options.  West Houston Dermatology’s, Dr. Stephen Mahoney is an excellent board certified dermatologist who specializes in treating psoriasis patients and is connected to the psoriasis research community so that he is aware of the most effective treatment options for his patients.
